Default [Q] Hisense 7 LT root help

Hey everybody! I am absolutely new to android experience and i was really bummed when on my Hisense 7 LT tablet i only had 1 GB of data for apps on it. I wanted to get link2sd so i may be able to do that. The only problem is that i am a complete newbie when it comes to rooting and android devices. I would need the most help i can get.

I found this forum thread that tells you how to do it but i am way to inexperienced to know what in the world i am supposed to do.

If i am doing everything wrong by asking this question plz tell me

oh and this is the last thing. the model number for my tablet is E270BSA
